In a groundbreaking showcase of technological innovation, William Li, the co-founder and CEO of NIO, personally tested the new 150 kWh battery pack in the NIO ET7 large sedan. Li, accompanied by his co-driver, achieved a remarkable 1,044 km (650 miles) range with 3% battery capacity remaining. While some media outlets are saying it is a semi-solid-state battery, NIO has not officially commented on the battery chemistry.

The test occurred during a nationwide cold wave, adding a layer of challenge to the accomplishment. Departing from the Shanghai World Expo Center battery swap station at a chilly -2 C° (28.4 F°), the team embarked on a 14-hour journey with an average cabin temperature of 20C° (68F°) through various cities and service areas, ultimately reaching the Longjudong service area in Xiamen City, Fujian Province.

According to NIO, the 150 kWh ultra-long range battery pack exhibited exceptional performance, exceeding expectations and proving the capabilities of the new battery technology, which has a single-cell energy density of 360Wh/kg and has six times faster cooling efficiency than conventional batteries. While some media outlets are saying it is a semi-solid-state battery, NIO has not officially commented on the battery chemistry. "This battery is currently the battery pack with the highest energy density in mass production in the world and has excellent safety performance," Li stated while live streaming.
